Phosphorus – an important macronutrient, is abundant in several soils and is one of the major nutrients limiting the plant growth. The overall Phosphorus use efficiency following phosphate fertilizer application is low because of the formation of insoluble complexes Therefore this mandate frequent application of soluble forms of inorganic Phosphorus necessary for crop production. This results in leaching to the ground water and results in eutrophication of aquatic systems and pollutes soil.
P Sol B® - BM aids in transformation of soil Phosphorus into an assimable form and is therefore an integral part of the soil Phosphorus cycle as they help in releasing Phosphorus from inorganic and organic pools of total soil Phosphorus through solubilization and mineralization.
P Sol B® - BM contains endospores of Bacillus megaterium . The composition is customised to comply with regulatory guidelines of respective countries. Bacillus megaterium is a proprietary strain and compliant with National Bio Diversity Authority guidelines and has Access Benefit Sharing (ABS) agreement with the State Bio Diversity Board for payment of royalty to the habitat from where the microbes have been isolated. The strain is under Patent deposit certificate with Budapest Treaty recognised depository
Carbon utilization:The bacteria contained in P Sol B® -BM on application to the soil get activated and multiply by utilizing the carbon source of soil or exudates of the root and in this process secrete organic acids and enzymes
Metabolite production:Bacillus megaterium produces organic acids such as lactic acid, gluconic acid, citric acid, succinic acid, propionic acid and enzymes that help solubilize the fixed phosphorus into exchangeable form. These organic acids through their hydroxyl and carboxyl groups chelate the cations (mainly Calcium) bound to phosphate converting them into the soluble forms.
An inverse relationship is observed between the pH and soluble-Phosphorus concentration which indicates that organic acid production by phospho bacteria plays a significant role in the acidification of the soil medium facilitating Phosphorus solubilization and easier assimilation by plants.
P Sol B® - BM is available in the following formulations:

P Sol B® - BM with crude sugar in sufficient water to make a slurry and coat seeds and dry in shade and sow / broadcast / dibble in the field. Do not store treated / coated seeds more than 24 hrs
1. Mix at recommended doses with compost and apply at early life stages of crop along with other biofertilizers
2. Mix P Sol B® - BM at recommended doses in sufficient water and drench soil at early leaf stage/ 2-4 leaf stage / early crop life cycle
3. Drip Irrigation: If there are insoluble particles, filter the solution and add to drip tank.
4. Long duration crops / Perennial / Orchard crops: Dissolve P Sol B® - BM at recommended doses in sufficient water and apply as a drenching spray near root zone twice a year. It is recommended to have first application before the onset of the main monsoon / rainfall/ spring season and second application after the main monsoon / rainfall / autumn/ fall season.
